of these particles and these, all flying apart, is awesome. the energy that takes to light up new york city comes about as a result of water pouring over niagara falls. and every water drop has an energy of about this much, four electron volts. electron volts are tiny unit of energy. it's microscopic unit of energy, yeah? but four electron volts per water drop, tnt-- [makes sounds] --you get about 30 electron volts. high-octane gasoline, about 30 electron volts per molecule of combustion, yeah? one atom, u235, fissions, you get about 200 million electron volts of energy. awesome, awesome. an awful lot of energy for one atom, and that kinda changed the world. and so we now talk about the atomic age or more properly the nuclear age because we're talking about an awful lot of energy for just a little bit of matter. it turns out the most common isotopic uranium is uranium-- let me try it over here-- uranium 238. and when 238 catches a neutron, what it does is it turns to u239. u238 emits alpha particles, but 239 emits beta particles. and guess what the 239 does, gang? it turns into an element beyond
